Asimple regressionmodel could be a linear approximation of a causative relationship between two or additional variables. Regressions models are extremely valuable, as they're one in every of the foremost common ways that to create inferences and predictions. 一个简单的回归模型可以是两个或其他变量之间...
We are basically telling the machine to use the linear regression model and learn from our set of data points in our training sets.The machine is learning! Now that ourregressorobject has learned from our training sets, we would want to examine how accurately it can predict new observations....

Linear regression is a simple model because it has few parameters. The Linear Regression parameters are their coefficients and intercept. Depending on the number of features we train, Linear Regression would haven+1parameters (n is the number of feature coefficients plus 1 for the intercept). ...
